Kugwiritsa ntchito ufa wa polima wosakanikirana ndi zinthu zina

Ufa wa rabara umapangidwa ndi kutentha kwambiri, kuthamanga kwambiri, kupopera mankhwala opopera ndi homopolymerization ndi mitundu yosiyanasiyana ya ufa wowonjezera mphamvu, zomwe zingathandize kwambiri kulimbitsa mgwirizano ndi mphamvu yokoka ya matope. , magwiridwe antchito abwino kwambiri okalamba kutentha, zosakaniza zosavuta, zosavuta kugwiritsa ntchito, zimatilola kupanga matope osakaniza ouma abwino kwambiri. Kugwiritsa ntchito ufa wa polima wosakanikirana ndi:

Zomatira: zomatira za matailosi, zomatira zomangira ndi zotetezera kutentha;

Mtondo wa pakhoma: matope otenthetsera kutentha akunja, matope okongoletsera;

Dothi la pansi: matope odzisankhira okha, matope okonza, matope osalowa madzi, chothandizira mawonekedwe a ufa wouma;

Zophimba za ufa: ma plaster a lime-simenti ndi zophimba zosinthidwa ndi ufa wa putty ndi ufa wa latex wa makoma ndi denga lamkati ndi lakunja;

Chodzaza: grout ya matailosi, matope olumikizirana.

Ufa wa latex wosungunukansoSichiyenera kusungidwa ndi kunyamulidwa ndi madzi, zomwe zimachepetsa ndalama zoyendera; nthawi yayitali yosungira, antifreeze, yosavuta kusunga; kuchuluka kochepa kolongedza, kulemera kopepuka, kosavuta kugwiritsa ntchito; Itha kugwiritsidwa ntchito ngati premix yosinthidwa ndi utomoni wopangidwa, ndipo imangofunika kuwonjezera madzi mukamagwiritsa ntchito, zomwe sizimangopewa zolakwika pakusakaniza pamalo omanga, komanso zimathandizira chitetezo cha magwiridwe antchito azinthu.

Mu matope, cholinga chake ndi kukonza kufooka kwa matope achikhalidwe a simenti monga kufooka ndi kusinthasintha kwakukulu, ndikupatsa matope a simenti kusinthasintha bwino komanso mphamvu yomangirira kuti apewe ndikuchedwetsa kupanga ming'alu ya matope a simenti. Popeza polima ndi matope amapanga kapangidwe ka netiweki yolumikizana, filimu yopitilira ya polima imapangidwa m'ma pores, yomwe imalimbitsa mgwirizano pakati pa ma aggregates ndikutseka ma pores ena mu matope. Chifukwa chake, matope osinthidwa pambuyo pouma amakhala ndi magwiridwe antchito abwino kuposa matope a simenti.

Ufa wa polima womwazika umabalalitsidwa mu filimu ndipo umagwira ntchito ngati cholimbitsa ngati guluu wachiwiri; colloid yoteteza imayamwa ndi makina a matope (filimuyo sidzawonongeka ndi madzi pambuyo popangidwa filimu, kapena "kufalikira kwachiwiri"); utomoni wa polima wopanga filimu Monga chinthu cholimbitsa chimagawidwa mu makina onse a matope, motero kumawonjezera mgwirizano wa matope.
